British Airways uses Foursquare for Grand Central pitch-up

British Airways appears to have found a use for location check-in service Foursquare and is running a promotion today to get people to an event in New York’s Grand Central Terminal.

The idea is quite simple, in some respects. The airline is currently hosting a contest for small business owners to film a 90-second pitch telling explaining where they would most like to fly and why it would benefit the company.
